Hiring extra help can be exciting — it means your business is growing and you’re getting busier. But even short-term or part-time hires come with payroll responsibilities. I’ve seen too many small business owners run into avoidable problems simply because they assumed seasonal or temporary employees didn’t need the same setup as full-timers.
Whether you’re bringing someone on for the busy season, a special project, or to help your team handle extra workload, here are five payroll mistakes to avoid.
1. Misclassifying Workers
This one trips up more small businesses than you’d expect. If you control how, when, and where someone works, they’re probably an employee, not an independent contractor. The difference matters because employees require tax withholding, payroll reporting, and coverage under labor laws. Misclassification can lead to penalties, back taxes, and frustration for everyone involved.
2. Skipping New Hire Reporting
Every state requires employers to report new hires — even if the person only works a few weeks. The process helps states track things like child support or wage garnishments. It’s quick, simple, and usually done online through your state’s labor department. Forgetting to report can result in fines, so it’s worth adding this step to your onboarding checklist.
3. Ignoring Overtime Laws
Just because someone is part-time or temporary doesn’t mean overtime rules disappear. Under the Fair Labor Standards Act (FLSA), most employees must be paid 1.5 times their regular rate for hours worked over 40 in a week, unless they qualify for an exemption. Check both federal and state rules to make sure you’re paying correctly.
4. Missing Payroll Tax Setup
Even short-term employees need to complete Form W-4 so you can withhold the proper federal income tax, Social Security, and Medicare. Setting this up correctly at the start prevents IRS notices or late payment penalties later. Make sure your payroll system is configured before their first paycheck.
5. Not Keeping Payroll Records
Good recordkeeping is your safety net. Employers are required to keep payroll records for at least three years, including hours worked, pay rates, deductions, and tax forms. Whether you store them digitally or on paper, make sure they’re organized and easy to access in case of an audit or employee question.
Even if your seasonal or temporary hires stay only a few months, treating payroll seriously protects both your business and your workers.
